Multiple Project Dependency Management in CMake
In a project with numerous subprojects that use shared libraries, managing dependencies can be a challenge. CMake provides several options to establish dependencies among projects.
Separate Project Method
If the libraries are not actively under development, consider creating separate CMake projects for each library. This isolates library development from the main project and simplifies dependency management.
Integrated Project Method
For ease of development, incorporate the libraries into the same CMake project as the main application. However, this requires careful dependency ordering and assumes that adding a library's subdirectory creates a ready-to-use target.
Recommended Best Practices
Dependency Setup
Separate Project Method:
Integrated Project Method:
Hybrid Approach
A mix of both methods is possible, allowing for flexibility in dependency management. Consider using ExternalProject for externally built libraries that are not installed.
